Gravitational waves from very massive stars collapsing to a black hole
Haruki Uchida, Masaru Shibata, Koh Takahashi +1
We compute gravitational waves emitted by the collapse of a rotating very massive star (VMS) core leading directly to a black hole in axisymmetric numerical-relativity simulations.…
Black Hole Formation and Explosion from Rapidly Rotating Very Massive Stars
Haruki Uchida, Masaru Shibata, Koh Takahashi +1
We explore the formation process of a black hole (BH) through the pair-instability collapse of a rotating Population III very massive star in axisymmetric numerical relativity. As…
Gravitational Collapse of Rotating Supermassive Stars including Nuclear Burning Effects
Haruki Uchida, Masaru Shibata, Takashi Yoshida +2
Supermassive stars (SMSs) of mass are candidates for seeds of supermassive black holes found in the center of many massive galaxies. We simulate the gravitat…
Gravitational waves from supermassive stars collapsing to a supermassive black hole
Masaru Shibata, Yuichiro Sekiguchi, Haruki Uchida +1
We derive the gravitational waveform from the collapse of a rapidly rotating supermassive star (SMS) core leading directly to a seed of a supermassive black hole (SMBH) in axisymme…
Stability of rigidly rotating supermassive stars against gravitational collapse
Masaru Shibata, Haruki Uchida, Yuichiro Sekiguchi
We revisit secular stability against quasi-radial collapse for rigidly rotating supermassive stars (SMSs) in general relativity. We suppose that the SMSs are in a nuclear-burning p…
